| dc.description | The main objective of this research is the development and application of a linked hydrodynamic-water quality model that can simulate the unique characteristics of small lakes, reservoirs, and tidal inlets and to study the mixing and transport of piped wastewater discharges. | en_US |
| dc.description | This thesis describes the hydrodynamic and water quality model formulations, and documents the equations and assumptions underlying the model development. The hydrodynamic model simulates the circulation in the water body and the water quality model mimics the constituent water quality variations such as dye, bacterial, and suspended solids concentrations. These models developed were applied to simulate advective and diffusive transports of conservative and non-conservative pollutants in a typical small lake, such as, Long Lake (Nova Scotia) and a typical small tidal inlet, such as, Parr Inlet (North West Territories). | en_US |
| dc.description | Long Lake has a complicated coastal configuration, and seven major streams of noticeably different water quality, empty into this lake. Many of these streams are on opposite sides of the lake and lateral averaging would combine them and therefore water quality changes will not be properly represented. This model mimics the unique characteristics of small lakes, reservoirs and tidal inlets and uses an alternating direction implicit scheme and vertically varying eddy viscosity (VVEV) scheme to compute vertical profiles of currents. This personal computer based three-dimensional model provides a computationally feasible and reasonably accurate alternative to other layered three-dimensional models. | en_US |
| dc.description | The main mass transport in Long Lake is due to wind, and the circulation caused by stream inflow/outflow contributes to a relatively small fraction of the total mass transport. The linked hydrodynamic-water quality model responses were studied for generation of currents, seiches, wind set up, and to contaminant loading. Both theoretical and experimental methods were used to evaluate the reliability of these models in predicting the hydrodynamics and water quality behavior. The theoretical methods developed were validated using both comparisons with analytical solutions (impulse, step and sinusoidal loading), and the experimental data gathered from the field. Drogue, water level, and water quality measurements were made at several locations in Long Lake as part of the experimental program. The linked hydrodynamic-water quality model was applied to Long Lake and Parr Inlet and the results of the simulations of water level/tidal elevations, streamflow/tidal/wind driven currents, and water quality variations are presented.
